Which should you choose?
Choose ShaamAI Humanizer if…
- • You have AI-generated text that needs to read as human to a detector
- • You want iterative rewriting — not a one-shot paraphrase
- • You want grade-level targeting and a style-matched Ultra mode
- • You’re cost-sensitive — $0.99/mo beats the typical ~$9.95/mo
- • Privacy matters — you don’t want drafts sitting in a third-party database
Choose QuillBot if…
- • You want a general writing suite (grammar, paraphrase, summarize, cite)
- • You need a Chrome extension or Microsoft Word integration
- • Your primary use is grammar polish, not detection evasion
- • You’re editing human drafts, not rewriting AI-generated ones

Unlimited paraphrasing, writing suite
General-purpose; not tuned for AI-detection evasion
Comparison FAQ
Does QuillBot’s paraphraser evade AI detection?
Not reliably. QuillBot is a general-purpose paraphraser, built to reword sentences for clarity, grammar, or tone — not specifically to defeat AI detectors. Paraphrased output often retains the statistical fingerprints (burstiness, perplexity distribution, lexical patterns) that modern detectors key on, and multiple user reports note the text still flags as AI-generated. ShaamAI’s Humanizer was designed from the ground up for this task, using iterative detection feedback to rewrite until the signal drops.
Is ShaamAI’s Humanizer cheaper than QuillBot Premium?
Yes, substantially. ShaamAI Pro is $0.99/month and includes 500,000 humanizer words per month. QuillBot Premium is approximately $9.95/month (verify current pricing at quillbot.com). For anyone who primarily needs to humanize AI-generated drafts, the price-per-word gap is large, and ShaamAI’s free tier (5 uses/month, up to 500 words each) is more generous than QuillBot’s free paraphraser word-count cap.
Can I use ShaamAI Humanizer for grammar checking too?
No — ShaamAI is deliberately focused. The Humanizer rewrites AI-generated prose to read as human, and the Detector flags AI-generated text; neither is a grammar checker, summarizer, or citation tool. If you want a full general writing suite, QuillBot (or Grammarly, LanguageTool) covers that surface area. If you want the best tool for the specific job of making AI text pass detection, ShaamAI is the better pick.
Which tool is better if my text needs to pass GPTZero or Turnitin?
ShaamAI Humanizer. It was engineered for exactly this workflow: it rewrites the text, scores the rewrite against a detection model, and keeps iterating until the score drops. QuillBot’s paraphraser applies a single pass of rewording without a detection-feedback loop, so there’s no systematic pressure on the output to look less like AI to a classifier. No humanizer can guarantee a pass on every detector forever, but iterative humanization is the design that targets the problem. See our GPTZero comparison for detection-side context.
Does QuillBot store my text?
QuillBot’s privacy policy allows for retention and processing of submitted text; details vary by plan and change over time, so check their current policy. ShaamAI does not save your input or output to any database, does not use it for training, and does not share it with third parties. Only anonymous metadata (word count, grade level, pass/fail signal) is retained.
Can I use both tools together?
Yes, and a fair number of users do. A common workflow is: draft with an LLM → run QuillBot for grammar and light paraphrasing polish → run ShaamAI Humanizer as the final pass to reduce AI-detection signal. The two tools aren’t mutually exclusive, and nothing about ShaamAI’s pricing or terms requires you to cancel QuillBot to use it.
